Industry News >> how is nylon fabric made?
The process begins with carbon-based (organic) chemicals, usually coal or petroleum. Certain polyamides can be produced from renewable carbon-based chemicals such as castor oil. In this case, organic means that the substance contains carbon. It isn’t the type of ‘organic’ label you see in the grocery store.
Heat and pressure are applied to the organic chemical to polymerize two large molecules found within it. These molecules are adipic acid and hexamethylenediamine. Polymerization is a chemical reaction in which smaller molecules combine to form a larger molecule. The structures of the smaller molecules are still present in the larger, resulting molecule. For example, our adipic acid = A and hexamethylenediamine = H. The chemical process adds these two together (A+H+A+H+A+H) resulting in a polymerized product (AHAHAH). So A+H doesn’t produce K, but AH.
The polymerization of these two molecules produces the nylon in the form of large ribbons or sheets. Then, these ribbons and sheets are shredded down to chips. If the nylon fiber’s final purpose is to become a textile, the chips are melted down and then forced through spinnerets to create fibers. Spinnerets are kind of like noodle makers for p
